Surprised I didn't see more in Java over the decades but I suspect that's because those old Sun/Oracle guys would prefer to go fishing than argue about who is more woke or whose agenda is more insidious.
You're very naive if you think at a place like Oracle there's no conflict, rivalries, and bitter arguments.
At my previous job we had enough drama that the police showed up at the office. Over a year we had screaming, insults, people climbing on the desk and throwing a monitor, and people in management getting into a serious fist fight with a broken nose. Plus a colorful employee who couldn't get his mind out of the gutter and apparently corporate property theft.
That was one surreal year, I've got to say, after which I changed jobs.
Only none of that happened on a public mailing list, so the only place where you'll hear even a hint of that is here from me.
